FINE GRANULAR FEEDS FOR FRY

摘要

Fine granular feeds for fry capable of remarkably elevating the survival rate of fry, elevating the pisciculture efficiency, and causing little elution of nitrogen sources therefrom into seawater or water in feeding. These feeds are characterized by containing at least two active components, i.e., (a) a long-chain unsaturated fatty acid calcium salt blend comprising 80 % by weight or more of long-chain unsaturated fatty acid calcium salt(s) having at least 18 carbon atoms and 20 % by weight or less of a browned matter formed by heating molasses or saccharides, a browned matter formed by heating saccharides with amino acids or a mixture thereof at an arbitrary ratio, and (b) a mixture of peptides obtained by hydrolyzing animal protein, and being in the form of fine grains.
